Characteristics of SinteredMetal Filter Media

Controlled Pore Size

All sintering is performed inhigh temperature vacuum orcontrolled atmosphere furnaces.Once the material is sintered,the pore size is fixed and thefilter medium will produceconsistent, reliable removal.To ensure absolute retentionratings, each grade of mediumis tested by the bubble pointtechnique, which correlates tothe largest diameter hard sphericalparticle that can pass throughthe medium.

High Pressure and TemperatureCapabilities

Inorganic media are inherentlystrong and, when properlysupported, can provide filtrationproducts capable of withstandingvery high differential pressures –up to 10,000 psid (690 bar). Oneof their outstanding characteristicsis the extreme temperatureswhich they can tolerate.Temperatures can range fromcryogenic, as low as -450°F (-268°C), to temperatures inexcess of 1500°F (816°C),depending upon the metal alloy used, the type of mediumselected and the atmosphere towhich the media will beexposed.

Why Inorganic Media?

Freedom from Extractables

Unlike polymeric or resin impregnated media, Pall metallic filtermedia will not contribute soluble or extractable materials to contaminate or impart taste or odor to the filtered product.

Freedom from Media Migration

All Pall sintered metal filters are free from particle or fiber sheddingand will not contaminate the filtrate.

Corrosion Resistance

Stainless steel is the standard material of construction; it exhibitsexcellent corrosion resistance in most fluids and service conditions.As the result of our superior metallurgical and sintering techniques,all of our stainless steel metal media is produced with a maximumcarbon content of .03%. Our sintering process is very effective inminimizing carbon content; thus, chromium carbide precipitation atthe metal boundaries, which causes intergranular corrosion, is keptto a minimum. This results in a porous metal media with longer in-service life. Slight variations in operating conditions, especially thoseassociated with system upset, can have a major impact on corrosionresistance. For existing systems, samples can frequently be suppliedfor long-term exposure and verification of alloy selection.

To ensure the highest quality end product we monitor all incomingraw materials. Porous metal powder is analyzed, not only for its metallurgical composition, but also for particle size distribution,which is critical to the end product. In the case of woven wire mesh, metallurgical properties are monitored, as is the weave andwire diameter. Control of metallurgy and wire diameter are also vital to fiber metal filter media.

In the case of 316L materials, carbon content is checked before and after the sintering operation. Each production lot of material is bubble point tested to measure the maximum size of a hard spherical particle which would pass, as well as being tested for permeability, thickness, and carbon content.

Pall PSS 316L Stainless Steel Medium is produced by a proprietarysintering process. No binders or other extraneous substances areintroduced, nor is pre-compression of the powder employed prior tosintering. The result is metallic material with a lower pressure drop ata given flow rate and approximately 20% more open area per unitarea than other sintered metals of similar efficiency. By controllingcarbon content, the finished product qualifies as 316L grade, which isless susceptible to carbide precipitation at the metal’s grain boundaries.Excellent corrosion resistance results; this ensures longer in-service life.

Pall PSS media are available in six standard grades with absoluteremoval ratings in liquid service from 55 micrometers (coarsest grade)to 5 micrometers (finest grade).

In addition to the standard 316L medium, most PSS grades can be furnished in the following alloys:

Rigimesh medium is a sintered woven wire mesh product having thegreatest permeability for comparable removal efficiency. Sintered in a high temperature vacuum furnace, the wires are bonded at everypoint of contact to produce an extremely strong metallic mediumwith wires that will not shift under stress; thus, the pore size andintegrity is continuously maintained. Since sintering increasesmechanical strength, this patented Pall process permits the use offiner diameter wires in manufacturing the medium. The result is afilter with greater dirt holding capacity and permeability than thatof an unsintered mesh of comparable removal rating.

We have the ability to sinter multi-layer composites of differentmeshes on special order, to meet application needs for precise flow,pressure drop, thickness, or strength.

Supramesh Medium is a combination of Rigimesh woven wire meshwith stainless steel powder sinter-bonded to its upstream surface.This results in a material that provides exceptionally fine depth filtration, complete freedom from media migration, and extremelylow pressure drop.

Our standard alloy for both Rigimesh and Supramesh is type 304Lstainless steel, with 316L and other alloys available on special order.Removal ratings for Rigimesh range from 18 to 450 micrometersabsolute in liquid service.

0.1 micron Zirconia coated stainless steel AccuSep medium. The Zirconia layer isonly available on the inside diameter of the tube.

AccuSep filter media offers the same high permeability as Pall’s S Series PSS® medium at a lower cost. AccuSep filters are more economical for many applications because they are manufactured ascontinuous length, seamless 48 or 96 inch long tubes, as opposed toshorter modules that are welded together. In addition, an AccuSepfilter system can be smaller than other offerings, since more filterarea can be packed into the vessel because of the small 1/2 ″ and3/4 ″ tube diameters available.
